Ethofocus-location along a fault where an eq happens;epicenter- location directly above ethofocus;elastic rebound theory-theory that explains why eq's happen; what does this theory say?- Stress builds up on either side of fault/plate boundary, then is rapidly fault/plate boundary, then is rapidly released causing earthquake. Rocks released causing earthquake. Rocks rebound back to original shape;A large building built on wet, loose sediments would have the most damage in a large eq; why?-liquifaction; A reverse fault would most likely be found in the area of a convergent boundary; why?- Convergent boundaries experience compressional stress (two sides stress (two sides pushing together). This is the kind of stress that forms reverse stress that forms reverse faults; Both P and S waves tell us about the interior of the earth because(both waves travel through the earth's interior) the S wave shadow states that S waves do not travel through liquid, when they hit the liquid outer core......
